Serial No. 429,274.

My invention relates generically to lumbermill machinery, and moreparticularly to a device for discharging the stickers which are used tospace the courses of lumber in a pile from each other,semi-automatically upon the pile as the courses are piled.

rI'his is a preliminary to the kiln-drying or stacking of lumber, andsince in the course of Acuring or drying the lumber it is most subjectto warping, cracking and the like if itis subjected to undue or unevenstresses,

it is particularly important that the stickers be evenly spaced and thateach sticker lie immediately above the sticker supporting the ,15 coursebelow throughout their lengths. It is the object of my invention toprovide a feed or discharge means, whereby the placing of the stickersin exact position is accomplished semi-automatically and with greatease, thus 2U eliminating considerable labor and the uncertainties ofthe human element.

It is a further object to provide a device of the general characterindicated above which may be easily adjusted to accommodate differentlengths of luniber,that is, to deposit the stickers at such differentspacings as may be desired.

A further object is the provision `of a piling system, including such asticker-depositing mechanism, wherein the pile may be kept always insuch position relative to the sticker magazines that lits upper courseis at a predetermined level therebelow.

Other objects, and more especially such as f" pertain` to the morestrictly mechanical details of my invention, will be discovered from astudycf the attached drawings, of this specification, and of the claimswhich terminate the same. 4G My inventioncomprises the novel parts ofV"a'novel combination and arrangement thereo In the accompanyingdrawings I have shown my invention in a form which is now preferred byme. y

Figure `1 is a view of a sticker magazine, lookingptoward'the end ofthelumber which is beingpiled, and showing parts in thepositions they wouldassume as a sticker is being discharged.

Figure 2 is a general view of the stickerdepositing mechanism, taken atright angles to Figure l, and showing the parts in their normalposition.

Figure 3 is a transverse section online 3-3 of Figure l through asticker magazine, parts being shown in the normal position, and F igure4 is a similar view, showing parts in operative position.

As the device would normally be incorporated in a mill, the lumber wouldbe piled upon a truck or car 9, mounted upon rollers or supportingwheels 90, by which it may be run along rails 91, carried upon anelevator platform 92. The elevator platform 92 may e supported andelevated in any suitable way, and merely as illustrative of one meanswhich may serve the purpose, I have shown a chain 93, connected to theplatform 92, and passing over a sprocket wheel 94, which may itself beconnected to a suitable source of power (not shown) to raise theelevator, or which may be merely a guide sprocket wheel, the oppositeend of the chain 93 passing to some other source of power. Adjacent theelevator platform is the working platform 95 and a feed table 9G, bymeans of which the lumber may be brought for piling upon the carplatform 9. The individual boards l are illustrated in the drawings withthe transversely extending sticker S between them, adjacent their ends,and at 'intern'iediate locations.

Above the elevator platform I prefer that overhead rails SO besupported, upon the beams 81, these rails 8() supporting the trackrollers 82 carried in trucks 8, wherecn, by means of transverse bars orbeams 83, the sticker magazine l is suspended in position transverselyof the pile of lumber on the platform 9. By thus supporting the stickermagazines, they may be moved into and out of position as and whenrequired, and their use may be dispensed with whenever it is not deemednecessary or convenient to employ them. Also, as will appear hereafter,it is possible more easily to adjust them in position with respect tothe pile of lumber and with respect to each other.

rlhe precise construction of the sticker plungers 2 on the severalmagazines all operate simultaneously, and this, of course, ena

tails that the several guide means 3 and 30 be simultaneously operable.To accomplish this, and yet to permit the adjustment al-f ready spokenof in the spacing between the magazmes,1 provide a rod 6, adjustable inlength, which `connects from oneinagazine to another. This mayconveniently consist of a` pipe, of which different lengths areprovided, the ends of the sections being secured to a fittingO,pivotally supported upon an arm 61,

secured upon theprimary rock shaft 4 and similar iittings()1 and arms61', by means of which the connection is made to the several rock shafts4, on succeeding magazines. To adjust the spacing of the magazines,then, it is only necessary to take out the section of pipe 6, and tobring the magazines together or to spread them apart and then to connectanother appropriate length of rod or pipe 6. A telescopmg rod might beemployed to advantage.

It is'believed the o eration of the device and itsadvantages wi l novirbe obvious, and that no detailed description thereof will be necessaryat this point. Obviously, changes may be made, within the scope of theclaims, and still be Within my invention.
